Just a note: those mild symptoms included eye bleeding (the conjunctivitis they mentioned casually). And this symptom in humans is not isolated to this case of H5N1, it's relatively common in cases as of late.

The bleeding here is subconjunctival hemorrhage, which by itself is not all that rare or serious. You can get it from sneezing too hard. It's happened to me a bunch of times.

I take your point, that the suggestion in that case study is that the virus caused it directly (RTPCR from the conjunctiva tested positive for the virus). He did have a full-blown case of conjunctivitis, though.
